Exodus 21:8

אם רעה בעיני אדניה IF SHE BE EVIL IN THE EYES OF HER LORD — i. e. that she did not find favour in his eyes so that he might be induced to marry her (cf. Mekhilta). אשר לו יעדה means: [IF SHE BE EVIL IN THE EYES OF HER LORD] WHO OUGHT TO HAVE DESIGNATED HER to be his wife and ought to have married her, her purchase-money serving as the money necessary to contract a marriage (כסף קידושין). Scripture hereby implicitly tells you that it is his duty to designate her for himself, and since it makes no mention of the manner in which the marriage is to be contracted it implicitly tells you at the same time that she requires no other rite of marriage than the passing of the purchase-money from the master to her father (cf. Kiddushin 19a, Bekhorot 13a). והפדה means he shall afford her the opportunity to obtain her release from service — that he himself must cooperate in respect to the amount of her ransom. And what is this opportunity he has to give her? That he allows her a deduction from her ransom corresponding to the number of years she has served in his house, as though she were only hired by him. How can this be done? Supposing he had bought her for a maneh (one hundred shekels) and she had served him two years. We say to him: “You knew that she was to go free at the end of six years; it follows then that you bought the labour of each year for one sixth of a maneh. Now she has served you two years, that is the equivalent of one-third of the maneh: accept therefore two-thirds of a maneh as a ransom and let her go free out of your house (Kiddushin 14b). לעם נכרי לא ימשל למכרה means that neither the master nor the father has a right to sell her to another Jewish man (Kiddushin 18a), בבגדו בה SEEING THAT HE HATH DEALT DECEITFULLY WITH HER — If “he” means the master then these words signify: if he intends to deal faithlessly with her, i. e. if he does not intend to fulfil the commandment of “Jiud” (of designating her to himself). So also the father — he has no right to sell her to another man since he has dealt faithlessly with her as a father having sold her to this man (Mekhilta; Kiddushin 18b).

אִם־רָעָ֞ה בְּעֵינֵ֧י אֲדֹנֶ֛יהָ אֲשֶׁר־[ל֥וֹ] (לא) יְעָדָ֖הּ וְהֶפְדָּ֑הּ לְעַ֥ם נׇכְרִ֛י לֹא־יִמְשֹׁ֥ל לְמׇכְרָ֖הּ בְּבִגְדוֹ־בָֽהּ׃

If she please not her master, who has designated her for himself, then shall he let her be redeemed: to sell her to a strange nation he shall have no power, seeing he has dealt deceitfully with her.
